The HV Extreme Helmet-Mounted Ear Defenders (Low Attenuation) are the latest addition to our premium colour-coded hearing protection range. Designed for use with Portwest Endurance and Height Endurance helmets, these defenders clip on easily, offering a secure and comfortable fit for users working in environments where lower attenuation is required to prevent overprotection. With an SNR of 22dB, they provide reliable noise reduction while still allowing for environmental awareness—ideal for tasks requiring communication and alertness. The dual-pin adjustable system ensures a personalised fit with multiple positioning options, while the defenders can also be comfortably rotated to a stand-off position when not in use. Colour-coded cups support quick identification of attenuation levels across teams, and contrast styling gives the product a modern, high-visibility finish. These defenders strike the right balance between comfort, compliance, and day-to-day practicality on site.
